LOSS-OF-HEAD AND RATE-OF-FLOW GAGE.

No. 926,721; i

To all whom it may concern:

Be it known that I, Mono M. 'BoRDEN, a citizen of the United States,residing at Collingswood, in the county of Camden and State of NewJersey, have invented a Lossof Head and Rate-of-Flow Gage, of which thefollowing is a specification.

This invention is a gage for indicating the variation of head and rateof flow of liquids generally. In its present application it is used inconnection with a filter where it is. desirable to have indicated theloss of head and.

rate of flow, which vary through varying conditions in the filter bed.In its preferred form means are provided whereby piezometric columnscommunicate the different pressures which determine the loss of head andrate of flow to differential mechanisms comprising revoluble andlongitudinally movable shafts through which indicating devices areoperated.

In the accompanying drawings, Figure 1 is a sectional elevationrepresenting the invention, Fig. 2 is a sectional plan of thedifferential mechanisms, and Fig. 3 is a sectional elevation taken onthe line 33 of Fig. 2.

As represented in the drawings, the invention is applied to the filter 1discharging through the conduit 2 having the contracted section orthroat 3.

A tube 4 connects the top of the filter with a tube or chamber 5 risingto or above the maximum piezometric head at the connection. A tube 6connects a normal section of the efliuent conduit with a tube or chamber7 rising to or above the maximum piezometric head at its place ofconnect-ion with the conduit, and a tube 8 connects the throatof theconduit with a tube or chamber 9 which rises to or above the maximumpiezometric head at the throat.

A float 10, in the chamber 5, is connected by a cord or wire 11 with asheave 12, which has the hollow journal 13 revoluble in the' bearing 14,and a sheave 15 fixed to the j ournal is connected by a cord or wire 16with a Specification of Letters Patent.

weight 17 which acts as a counter balance for the float.

A float 18, in the chamber 7, is connected by a cord or wire 19 with asheave 20 fixed to a hollow journal 21 which is revoluble in the bearing22 and a sheave 28 fixed to the journal is connected by a cord or wire24 with a weight 25 to counter balance the float.

A float 26, in the chamber 9, is connected by a wire or cord 27 with asheave 28 fixed to a hollow journal 29 which is revoluble in the bearing29, and fixed to the journal is a second sheave 30 which is connected bya cord or wire 31 with a weight 32 for counter balancing the float.

The journal 13 and hub 13", connected with the sheaves 12 and 15, rovidea barrel which is internally threadec to receive the provided with thecylindrlcal rack 34" which engages a inion 35 fixedto a shaft or journal36, the atter being journaled in a bearing 37and carrying a pointer 38which moves over the graduated dial 39.

The journal 21, with the sheave hubs 21 and 23, provides a barrel whichis internally threaded to receive the end of a shaft 40 having thethreads 40, the opposite end of the shaft having thev spline connection40 with the hub 28 of the sheave 28. A cylindrical rack 40 on the bodyof this shaft engages a pinion 41 on a shaft 42 journaled in a bearing43, the shaft carrying a pointer 44 which moves over a graduated dial45.

The height of the column of liquid in the chamber 5, representing thehead at the influx to the filter bed, determines the position of thefloat 10 and the sheave 12. The movement of these parts, which isinduced by changes in head, is communicated through the screw 34 to movethe shaft-34 lon itudinally, whereby the pinion 35 and shaft 36 arerevolved to movethe pointer, 38 on the dial 3 9. The height of thecolumn of lic uid in the chamber 7, representing the hea of the effluxfrom the filter, determines the po siti'on-fof the float 18 and thesheave 20. Any-variation in the column effects a rotary and longitudinalmovement of the shaft 34 through its spline 34 and screw 34', where bythe inion35 and shaft 36 are revolved to move t e pointer 88 over thedial 39.

As the variations in. head shown by these piezometric columns aredifferentiated by the mechanisms subject thereto, the resultant pressureor head will be indicated by the ointer with the graduations on thedial. The loss of head, which results from the accumulation of foreignmatter or other obchamber 7 and the consequent struction in the filter,may thus be indicated.

The height of the column of liquid in the ositions of the float 18 andthe sheave 20 a cot the position of the shaft 40 which is movedlongitudinally by its screw 40 through the rotary movement of thesheave. The longitudinal movement of this shaft revolves the pinion 41and the shaft 42, whereby the pointer 44 is caused to move over the dial45.

The height of the column of liquidin the chamber 9 and the consequentpositions of the float 26 and sheave 28 also alfectthe position of thepointer 44, the rotary movementof the sheave being communicated by thespline 40" to the shaft 40 which is thus moved longitudinally by theengagement of its screw 40, whereby the pinion 41 and its shaft 42 arerevolved tomove the pointer 44 over the dial 45. I

The variations in'head, as shown by the piezometric columns of thechambers connected with a normal and the contracted section of theconduit, which'variations 'increase with any increase in velocity offlow, are thus differentiated and by suitably graduating the .dial thepointer will'indicate the rate of flow thereon.
